Detailed Description

The core of the specific embodiment is to provide an electronic tag, which improves the service life of the electronic tag and solves the problem in the field at the present stage.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Please refer to fig. 1-8 for the electronic tag provided in this embodiment; the method comprises the following steps: the antenna comprises a support 1, an antenna 2, a chip 3 and a shell 4; the bracket 1 is a non-conductor; the antenna 2 is wrapped on the lower surface of the bracket 1 from the upper surface of the bracket 1 and is provided with an exhaust hole 6; the chip 3 is arranged on the antenna 2 and used for identifying product information; the shell 4 is formed by a secondary injection molding process and wraps the bracket 1 to seal the electronic tag. The antenna 2 of the electronic tag is provided with the exhaust hole 6, so that residual air in the antenna can be exhausted in a high-temperature environment of a secondary injection molding process, and the problem that the service life of the tag is influenced by expansion of a finished product in the using process is avoided; and the shell 4 after the secondary is moulded plastics can make electronic tags wholly realize sealedly, avoids the inside life-span that influences electronic component of external steam entering label. Therefore, the utility model provides an electronic tags has improved electronic tags's life, has solved the difficult problem in this field at present stage.

In the manufacturing process, firstly, the bracket 1 can be manufactured through an injection molding process, and finally, the bracket 1 is placed in a mold for secondary injection molding to complete the process of wrapping the bracket 1 by the shell 4; when the support 1 is adhered to the antenna 2, residual air is possibly left between the support and the antenna, and the residual air is discharged due to high temperature in the injection molding process of the shell 4 due to the existence of the exhaust holes 6, so that the electronic tag is packaged in a sealed mode, and the service life of the electronic tag is prolonged.

In the outdoor electronic tag, the bracket 1 may be made of plastic or other non-conductor materials capable of playing a role equally; the antenna 2 can be a high-temperature-resistant flexible circuit board, so that the working performance of the antenna 2 is prevented from being influenced by a high-temperature environment in the process of secondary injection molding, the antenna 2 and the support 1 can be fixed together in a sticking mode, the antenna 2 can adopt polyimide as a base material, copper as a conducting layer, and the antenna is formed by composite pressing and etching.

In the electronic tag provided by the present embodiment, the length of the antenna 2 is smaller than the perimeter of the bracket 1, and the antenna 2 is wrapped from the upper surface of the bracket 1 to the lower surface of the bracket 1, that is, the antenna 2 can be wrapped on the upper surface, 1 side surface and the lower surface of the bracket 1 in a U shape, and a certain distance is left between two ends of the wrapped antenna 2; the design can make the upper surface of the bracket 1 form the radiation front surface of the antenna 2, and form the radiation bottom surface on the lower surface, and the front surface and the bottom surface are communicated through the connecting area on the side surface.

The circumferential length of the stent 1 refers to the sum of the widths of the upper and lower surfaces of the stent and the thicknesses of the two side surfaces of the stent 1.

Further, the length of the antenna 2 may be set according to actual needs, for example, the length of the antenna 2 may be designed to be about a quarter wavelength.

In the electronic tag provided by the present embodiment, the upper surface of the support 1 is in two steps that change slowly, that is, a higher step and a lower step are connected by a gentle slope.

Firstly, the gentle slope treatment is beneficial to the pasting of the antenna 2 in the area; secondly, because of antenna 2 wraps up in the upper surface and the lower surface of lower ladder during the design, so can increase the wall thickness of chip 3 top shell 4, and then improve electronic tags's weatherability.

In the electronic tag provided by the embodiment, the grooves 5 may be arranged on two sides of the higher step on the upper surface of the bracket 1, and the grooves 5 are arranged on two sides of the lower surface of the bracket 1; this design can avoid support 1 to shrink, and at the in-process that the secondary was moulded plastics simultaneously, messenger's shell 4 that can be better fuses with support 1 mutually, and then improves the holistic intensity of electronic tags.

Above-mentioned shell 4 and support 1 can be made for the same kind of material, and this setting can be at the in-process that the secondary was moulded plastics for shell 4 fuses as an organic whole with the surface of support 1 to improve electronic tags's self intensity, and then improve life.

Further, a plurality of exhaust holes 6 are formed on the upper surface and the lower surface of the bracket 1 on the antenna 2; and further be favorable to remaining the air discharge between antenna 2 and support 1, avoid the air to remain in electronic tags, cause the life-span to shorten.

In the electronic tag provided by the embodiment, the upper surface and the lower surface of the bracket 1, which are wrapped by the antenna 2, are parallel, that is, the folded antenna 2 is provided, and the antennas 2 on the upper surface and the lower surface of the bracket 1 are parallel, so as to improve the radiation effect.

In the electronic tag provided by the embodiment, the two ends of the lower surface of the shell 4 can be provided with the groove bodies 7 to prevent shrinkage deformation, so that the service life of the electronic tag is prolonged.

In the electronic tag provided by the embodiment, the upper surface and the lower surface of the support 1 are subjected to the pattern drying treatment, so that the roughness of the surface is increased, and the adhesion force between the antenna 2 and the support 1 is further enhanced.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
